Abstract
|
|
|
The evoked otoacoustic emission signals are measured and processed by compufer for analysis. Small microphone and earspeaker are inserted into outer car for the acquistion of E-OAE signals. After stimulations and detections are repeated 100
times,
the
signals are averaged for noise cancellation and analyzed on frequency domain and time domain. Automatic latency calculation algorithm is proposed and mathmatical functions are extracted from analysis of latency. These assure that latency is
directly
related to the impedance of
cochlear.
